We investigated the home-range size and habitat use of eight Sooty Owls (Tyto tenebricosa tenebricosa) in coastal forests in East Gippsland, Victoria, Australia, between November 2006 and January 2008. The size of home-ranges varied widely; based on 95% adaptive kernel estimates, the average size of home-ranges of males was 3025ha (±1194s.d., n=3), whereas that of females was 994ha (±654s.d., n=5). Sooty Owls utilised a broad range of ecological vegetation classes and topographical features for roosting and foraging at a greater scale than previously assumed. There was minimal selection for habitat types based on floristic composition, primarily only avoiding heathlands (for foraging and roosting) and selecting particular dense foliage (rainforest and riparian scrub) for foliage roosting. Two Owls maintained home-ranges close to logged areas, with logging regrowth (<45 years old) being strongly avoided by both individuals. We recommend that the size of individual reserves for Sooty Owls in commercial forests should be increased to more closely resemble the core spatial resource requirements needed by a pair. Reserves should be largest where they feed predominantly on hollow-dependent prey. Most importantly, rather than conservation measures just focussing on the spatial requirements of Sooty Owls, efforts should be directed towards retaining high densities of crucial resources, such as hollow-bearing trees and mammalian prey species throughout the landscape.

Both educators and education policies have long claimed a role in preparing students for ‘the future’. This has been referred to as the rhetoric of futures in education, as the notion of a future is assumed, abstract and not articulated (Bateman 2010). Recent research indicates that teachers give little attention to futures thinking in interpreting and enacting curriculum documents. Only when their ‘futures consciousness’ was increased were they able to generate explicit alternate futures scenarios and make connections with learners (Bateman 2012). In light of international education policy agendas pressing countries to adopt economic competitiveness in national curriculum policies, the ‘future’ vision looks narrow and constrained. We argue that current educational reforms in Australia provide little scope to address the concept of multiple futures, which are significant in enabling citizens to shape and contribute in personal, local and global contexts.

The assumption that all education prepares students for their futures is misguided. Rather, students are prepared, through curriculum and institutional practices for politically constructed notions of the future, which are often based on another assumption that what has worked in the past will continue to work in the future. This is evident in the absence of articulated futures within curriculum and other policy documents. This research showcases a critical ethnography which was undertaken in a Victorian primary school. The specific project focussed on the ways in which Year 5/6 classroom teachers reconceptualised curriculum to incorporate futures thinking as a result of ongoing professional learning and support. Through the use of analytical bracketing and post-analytic ethnomethodology for analysis across the data, the presenter proposes a conceptual model which highlights the complexity of this work as well as a theoretical explanation of why futures remains the missing dimension in education.

The use of commodity, currency and stock index futures to hedge risky exposures in the underlying assets is well documented in financial literature. However single stock futures are a relatively new addition to the family of futures and as such, academic research on its use as a hedging tool is relatively thin. In this study we have explored the efficacy of two different methodological approaches that may be applied when hedging a long position in the underlying stock with a single stock future. We use daily trading data covering years 2002 to 2007 from the Indian market, where single stock futures have been really thriving in terms of volume of trade, to extract the optimal hedge ratios using both static OLS as well as 30-day, 60-day and 90-day moving least squares. The method of moving least squares has been in use by market practitioners for some time primarily as a trend analysis and charting tool. Our results indicate that the moving least squares approach outperforms the static OLS in terms of the hedging efficiency, which has been measured by the root mean square hedging error.

The idea of sustainable development is distinct from the idea of restoring or conserving nature. This concept is embedded in the Rio Declaration on Environment and Development (1992) which Indonesia and several countries around the world have signed. Sustainable development seeks to interlace humans and nature, while restoration (especially at the large scale) often allows nature to be addressed separately, sometimes out of remorse for the damage caused by humans. In terms of attaining sustainable natural resource development, the opportunities offered by traditional ecological knowledge documentation are considered essential in enabling the achievement of sustainability because most of these Indigenous and/or local communities are situated in areas where many species have been historically cultivated and used in a sustainable way for thousands of years. The skill and techniques of these local communities can provide valuable information for the global community to evaluate current environmental policies. Such research and evaluation is often robustly and best undertaken through ethnoecological methodological paradigms. This paper examines the traditional environment knowledge of the Minahasan ethnic community, who live in the surrounds of Lake Tondano in the North Sulawesi, together with the Minahasan conscious and unconscious actions in conserving their forest ecology in addition to their knowledge of culture about forest protection in the region. In particular, contemporary use of traditional environmental knowledge is examined in terms of its relevance to in traditional resource management and land use planning, as avenues to better curate and manage natural resources through informed regional planning strategies and mechanisms.

The standard model linking the swap rate to the rates in a contemporaneous strip of futures interest rate contracts typically produces biased estimates of the swap rate. Institutional differences usually require some form of interpolation to be employed and may in principle explain this empirical result. Using Australian data, we find evidence consistent with this explanation and show that model performance is greatly improved if an alternative interpolation method is used. In doing so, we also provide the first published Australian evidence on the accuracy of the futures-based approach to pricing interest rate swaps.
